Hi and welcome to the open source HCFR software thread. 

This thread was originally started by JohnAd who had the nice idea of creating an open source fork of the original HCFR Colormeter software to integrate the existing GUI and all of it's calibration features, with the meter handling code of ArgyllCMS. Since ArgyllCMS is continually adding and improving meter support, HCFR benefits by staying current with these developments. The software is frequently referred to as HCFR or colorHCFR where HCFR is short for "Home Cinema-FR", a French forum where some of it's members originally developed the code to support their home-brew colorimeter in 2005. Along with the meter handling improvements introduced by ArgyllCMS, I have been working on improving and adding features to the color engine and internal pattern generator. Please use this thread for bug reports, usage questions and suggestions for improvement. Anyone wishing to help with code development should join the developers mailing list. 

The latest version of HCFR (3.1.5) can be found hereChangelog

FAQ: 
Do I need to install a driver for the i1Display Pro (i1D3)?
No. This meter as well as the Huey,  ColorMunki Display, and ColorHug use the system HID driver. 

Which probes are supported?
Any probe that ArgyllCMS supports.

How do I install the right driver for my probe?
Assuming your device is not one of those above, the driver .inf file is located in the drivers sub-directory of the main HCFR folder (by default this is c:\Program Files (x86)\HCFR Calibration\Drivers). You do not need to install the full ArgyllCMS program but usefull driver installation hints can be found here.

Which deltaE formula is the most accurate?
All the deltaE formulas represent a measure of the distance between your measured color and the reference color. So they are just rulers with different scales, use the one recommended if you aren't sure. For gray scale measurements the recommend formula provides more sensitivity to chromaticity (x,y) errors so it's easier to use for "tuning" your controls. The dE94 or dE2000 formulas are generally the most acceptable for "proofing" as they are the most uniform in perceptual space and a unit of error in one part of the gamut has the same visual impact as the rest of the gamut.

Cool. Good luck. I'm loving HCFR so much more now that I own a i1pro and Display2.

Support for display3 should be a priority.

Something easy could be more graph options and maybe report generation.

Long live the legend, HCFR!

It's not bad for freeware but cost aside I much prefer CalMAN or ChromaPure.

To each his own I guess. HCFR is a lot free-er.

( I don't think I'll ever choose CalMan but I would be happy to use Chromapure eventually. )



Back to suggestions: it's easy to profile my dispay2 to my i1 pro in HCFR, but it could be even easier if the process was better integrated.

I can test with ver 5.1 of the HCFR TAOS based probes as I have several. I subscribed to the dev forum. I can hack in VB and have 2008 visual studio that I would be interested in having a build environment working.

It's great to see this arising again.

My main gripe is that it needs updating and support for newer hardware. I do like however that it supports the i1pro spectro.

The killer notion would be: a Mac version!

CalMan and Chromapure are ignoring Apple.

I would help making an iPad version. (I'm not sure how but I would help anyway I could.)

Not sure about easy ...
At least initially I'll be focusing on opening the use meters up so the taking and sharing of readings is as easy as possible, this probably means dumping data out to spreadsheets for graphing/reports rather than building too many more screen in hcfr as at the moment each graph seems to be quite a lot of code.

There was a mac version, I just haven't got the code for that, I'm happy to try and restart that though if anybody has the source let me know.

Cool, should be just a question of installing git (I Use tortoisegit) and pulling the source from sourceforge and then building the project.

That's awesome!

I have the Mac version (not the source code though) but I think it supports even fewer meters. Like just the spyders

I read the above comments, and my main gripe with HCFR is that the red, green, and blue data on the luminance and gamma graphs is normalized. I think the non-normalized data when you choose the display RGB checkbox is a lot simpler to understand, but unfortunately new users typically find it easier to have graphs to represent the data. I consider it more intuitive to have one graph that represents the entire grayscale run, rather than trying to get new users to understand what two graphs represent (luminance and RGB levels). Maybe it's just me, but I think comparing non-normalized red, green, and blue plots to a target gamma curve is far simpler to comprehend the limitations of 2-point grayscale controls.

From what I remember, HCFR doesn't calculate dE's of colours correctly. You'd also have to manually calculate what the luminance level should be for each colour then adjust brightness to that.

Thanks for all the feedback so far, so quite a lot to do then

I've only really used it at a way of getting raw measurements so haven't really seen a lot of the issues metioned.

Correcting the dE and normalising side of things should be fairly straightforward, but I'd expect getting agreement on what's right to take longer....

I think HCFR excludes Y errors from dE, is that what you mean or is there a bigger issue?

Not sure what you mean here, is this for non-additive displays?

I don't think HCFR leaves Y out of color DE. Currently I have green with perfect xy and 30% Y error and de is high.

I'm not even convinced HCFR calculates color de wrong. This is something I could investigate. It's easy enough to manually put in the data thats correct and then modify it different ways.

Can you give a bit more of a description of what you mean, how you would see this working? Do you mean you pick which point you are doing and then working with continuous readings and a target?

Would you expect to normalize the luminance of the 100% or the 109% point?

So do 0% to get black, 109% to get peak and then do 100%, 90%... 10%

Sure would be nice to be able to put up 75%, 50% and 25% saturation points on the gamut chart since many use 75%.
This way using Continuous Measure to align hue and saturation would be simplified.

Looking through the code there seems to be some quite confusing labeling going on.

In the advanced tab, there are 2 settings at the bottom

The first of those "Do not use luminance in delta E formula (V1.x)" corresponds to the internal setting Use Old DeltaE so should be off.

The second of those is "Use gamma reference to compute gray scale delta E" should be on if you want Y to be included in dE and off if you don't.

The default for both is off so unless you change something Y is not included in dE.

I think what he means is actually a 9-point gamma real-time tracking for 10% - 90% (0% black and 100% white have no gamma value). Right now it is not convenient to do that because the target Y values are calculated only after a complete grayscale run from 0% to 100%. If I'm only adjusting the gamma of, say the 70% point, what I need to measure is the 0% Y value and the 100% Y value, and the target Y for my 70% point should be calculated and show up on the screen for me to shoot for that value (using continuous measure).

Yeah,... I use a secondary excel spreadsheet that I put in the 100% Y value and it gives me the rest for any gamma target. This way I can adjust other values without running the whole set of measurements.

There's no lack of things do suggest for HCFR since it's not been updated in years. Just enhancing the meter support would be HUGE.

[/QUOTE=Brian Hampton;21643233]Yeah,... I use a secondary excel spreadsheet that I put in the 100% Y value and it gives me the rest for any gamma target. This way I can adjust other values without running the whole set of measurements.

Same here - having to use a separate spreadsheet is a pain with HCFR, would be great to be able to use the HCFR 100%Y value and have the program calculate at least the 100% & 75% saturation levels for a gamma target, should not be too hard to do. Link to spreadsheet that shows how this is done: http://www.avsforum.com/avs-vb/showt...7#post15607437
Also support for the new Display-3 would be great. Just adding these two features would make HCFR useful for most of the basic DIY calibration tasks.

So do 0% to get black, 109% to get peak and then do 100%, 90%... 10%

I want it to be able to take the 100% Y reading and calculate the appropriate Y reading for each level down to 10% (90%, 80%, 70%, etc) so that I can adjust the level of Y at each level to match the calculated target to achieve the gamma I want at each level.

...and I want to be able to make these adjustments in real time without having to refer to a spreadsheet..

As it stands now, all you can do is do a full set of grayscale measures and see what the (average) gamma is and see the curve displayed on a chart. You can't see the results of any gamma corrections you make in real time. You can just guess at some corrections and then do another full set of grayscale measures, and keep repeating until you get a gamma reading you want.

Right now it is not convenient to do that because the target Y values are calculated only after a complete grayscale run from 0% to 100%. If I'm only adjusting the gamma of, say the 70% point, what I need to measure is the 0% Y value and the 100% Y value, and the target Y for my 70% point should be calculated and show up on the screen for me to shoot for that value (using continuous measure).

Yes, that is what I meant.

This may not be necessary. You can display the %stimulus pattern in question, e.g. a 70% window, use free measurement to observe the measured xyY value while changing your gamma setting for 70% in the TV/projector, and align the measured Y to the target gamma Y as shown in the measurement table.

If you suspect the 100% luminance level is changed, you can check the box "Editable data" in the measurement table, do a free measurement at the 100% pattern, copy-and-paste the measured xyY data (on the left side of the screen) to the column of 100% data, and all the target gamma Y values for 10% - 90% will be refreshed.

Of course, this will work only if you have done a complete grayscale run; and the process is too clumbersome.
